DOI: 10.1049/cp.2009.0520 ISBN: 978 1 84919 126 5 Location: Prague, Czech Republic Conference date: 8-11 June 2009 Format: PDF This paper describes the application of a static Var compensator to improve the electrical system of the Cravo Norte Association (A C N) Oil Field in Colombia. The static Var compensator (SVC) was installed at the receiving end of the 160 km - 230 kV power line that feeds the oilfield. The main benefits of the SVC installation are: 1) The electrical system is no more affected by the length of the line or the national grid voltage variations. The system voltage has been stabilized at 34.5 kV +/- 2%. 2) The power transmitted through the power line has increased by about 30 MW. 3) The SVC has added dynamic response to the system to voltage sags, load shedding or generator shutdowns. Variable speed drive shutdowns associated with voltage sags have been reduced by about 95%. 4) The SVC provides control of voltage unbalance to 2% at 34.5 kV The paper summarizes this application, including the system aspects that require special control functions in the SVC regulator. Some relevant design features of the SVC are treated, as well.
